Take the pseudoscience of sexual addiction treatment, and ratchet it up a notch with cruelty, and you get reparative therapy. This horrendous scam claims to use "therapy" to cure homosexuality. This gets our number one spot because it feeds off of the misery of gay people living in a homophobic society while promoting a fundamentalist religious agenda. While the sex addiction industry may be bigger, the individual cost to the person seeking treatment here is greater. Its a triple threat scam.

Treatment can be amazingly expensive, and since it basically does not work, you'll be in therapy a long time. Not only does it foster the assumption that homosexuality is a disorder, contrary to the general consensus of the medical community, it also ignores the existence of male bisexuality as a possible explanation of the very few documented "cures", and provides nothing in the way of documentation to demonstrate any overall effectiveness.
